Interface ResourceNameIterator

Iterate over resource names.
The semantics are somewhat unusual, for better or worse.
hasNext is presumed to be destructive to the current state,
each call will 'move' the cursor.
nextResourceName() MUST BE non-destructive,
it does not change the state.
TODO: FIX iterator logic/semantics, possibly add 'currentResourceName()'.
